The '''Mississippi Historical Society''' (MHS) is a historical society
located in the U.S. state
. The society was established in 1858 but was terminated due to the coming of the American Civil War. It remained in hiatus until 1890, publishing extensively over the next 35 years and helping to establish the Mississippi Department of Archives and History
in 1902. After a second protracted hiatus, lasting from 1925 until 1952, the society re-emerged and has remained in continuous operation ever since.
The society publishes the quarterly '''''Journal of Mississippi History''''', the monthly '''''Mississippi History Newsletter''''', and the online journal '''''Mississippi History Now'''''.
